TED’s Interactive Sculpture

If you’re not familiar with TED, it’s a non-profit organization dedicated to spreading ideas in the form of short powerful talks. This year’s conference in Vancouver, featured a large outdoor sculpture which was a collaboration between sculptor Janet Echelman and data artist Aaron Koblin. At night, people were able to interact with the sculpture using their phones to draw lines, webs, water drops, squiggles etc… onto the sculpture.

The data artist Aaron Koblin described the way it works in the article:

“The lighting on the sculpture is actually a giant website,” Koblin says. “It’s one huge Google Chrome window spread across five HD projectors. The content is being rendered in WebGL. It uses Javascript and shaders to render particles and sprites based on user motion, which is transmitted from mobile browser to our rendering browser via websockets. There are a lot of moving pieces here, from the local area network to the server (written in Go), to the sound system (also running in Chrome with Web Audio API) all the way through the LED light control system, which pulls pixel data directly from the browser.”

I highly recommend you read the entire article on the TED blog here & watch the video’s as well
